Hello Florian,
thanks for sharing this material. Reading the slides I am wondering about some details.
At page 5 is a gap in the lyrics of the gregorian chant (gi - na). The syllable 'na' is not centered on the note. Do you know the reason for this?
At page 13 we read that letters are notes. At page 20 letters migrate to pitches. I think the latter is correct. I know the picture comes from the 'official' Lilypond material. Probably this could be clarified.
At page 17 is a typo. You find the correct spelling here:

Regards
Helge
